Here, as Order III. of the Malacostraci, stand the Amfipodi, including " Phronima scdentaria. 

 Phronima custos. Phrosine semUunata. Orio zancleus. Coc. Sicilia. Orio oxyrhinchus, 

 Prest. iOT. Orio ornithoramphus. SciniY ensicorne, Prest. Sicilia. Cleistotoma Gemmellaii, 

 id. Orchestia littorea. Talytrus locusta. Lisianassa Costie, Edw. Gammarus pulex. 

 Gammarus marinus ? Dexamine spinosa. Leucothoe articulosa. Amphithoe annulata, n. 

 Sannazaria pallida, n. Callisoma punctata, n. Typhis ovoides. Anceus forficularius. 

 Praniza ccBruleata." As Order IV. stand the Lemodipodi, inchiding " Caprella pliasma. 

 CapreUa linearis. Caprella acutifrons. Cyamus acutifrons, n. Sicilia." No descriptions, 

 and in most oases no authorities. 



Costa's figure of Phrosina seinilunata, Eisso, " Fn. Nap. tav. IV, fig. 1-5," cannot be of later 

 date than 1840, as Milne-Edwards refers to it, Hist. nat. des Crust, iii., p. 91, with the 

 following observation, "la Phrosine semilunairc, k en jiiger par la figure trfes-detaOlee qu'en 

 a donnee M. Costa, differe de I'esp&ce precedente par I'absence d'une grosse dent k Tangle 

 antero-infericur du penultieme article des pates anterieures, par la forme plus acuminee des 

 lames natatoires que representent les trois dernitjres paires de fausses pates, et par quelques 

 autres caractires." The preceding species referred to by Milne-Edwards is his own 

 Phrosina Nicetensis. Costa himself in 1857 gives the following references, which are 

 probably all of later date than 1840 : — " Orchestia deshayesii, Aud., Edw., A. Cost. Faun. 

 Nap. tav. VIII bis, fig. 3"; Talitrus platijcheles, Guer. — A. Cost. Fn. Nap. tav. VIII 

 bis, f. 2."; " Lijsianassa Costa; 'Edw. — A. Cost. Fn. Nap."; "■ Callisoma punrtatum. Cost. 

 Fn. Nap. Tav. VIII, fig. 4-7"; ''Callisoma Hopei, A. Cost. Fn. Nap. Tav. VIII bis, 

 fig. 1." Leucothoe denticulata, A. Cost., " Fn. Nap. Tav. IX., fig. 3. (senza testo)." 

 Vihilia speciosa, A. Cost. "Fn. Nap. tav. IX, fig. 1 (senza testo).", and the Phrosina 

 already mentioned.

In the account of the orders Lsmodipodes and Amphipodes, pages 219 to 240, no original 

 information appears to be given. There is a full account of Gijamus, taken from Roussel 

 de Vauzeme. Of the Lsemodipodes filiformes the genera mentioned are Lqjtomera, 

 Naupredia, Caprella. In the definition of Leptomera, the legs " ne paroissent pas tons 

 pourvus d'appendices en forme de sac vesicideux h, leur base, ou meme n'en ayant pas du 

 tout." Of the species, Leptomera ventricosa, he says, " Cette espfece presente un appendice 

 en forme de lobe k tous les pieds, les deux premiers exceptes. M. Latreille lui rapporte 

 aussi I'espece representee par Slabber, Micros., tab. 10, fig. 2, etle Cancer Pedatus, Montagu. 

 Transact. Linn., t. xi, pi. 2, fig. 6, qui en a tous les pieds pourvus, moins ceux de la premiere 

 et des trois dernieres paires." Proto ventricosa, O. F. M., has in fact only three pairs of 

 branchiae, though Slabber figures it with six pairs. jVaujJredia is here as usual without a 

 species. 



In the account of the Amphipodes the first mentioned is OrcJiestia littoralis, with references to 

 Leach in the Edinb. Encycl. and the Linnaean Transactions, in both of which he remarks 

 that his Talitrus littoralis is the female of Talitrus locnsfa. Of Orchestia littoralis he 

 makes no mention. The name Gammarus fiuviaf His, M.-Edw., is used for the Squillapvlex
